Other good camo plants ive used are sunroot (jerusalem artichoke), pigeon pea (looks a bit like it and all my neibours are used to it).
Ive also used that technique of planting in weedy bush until the fkn landcare groups get in there and weed everything out. have done nice plants on waterfall cliffs in isolated bush. They are in full sun and able to get their roots in the creek, very hard to see and get to.
Would like to try training my thais into tall tall trees, so everyhting is up above the shrubline, with only a trunk visible. I'll remove very leaf and branch so the main tip gets all the energy. I'll leave a good foot or two of leafy top to power itself though.
Only use old variety sativas in the bush coz theyre hardy as hell and are very mould resistant, coming from SE asia and all.
And they are very, very sweet and bright hight.
